[mkgmap-dev] Crash "Illegal Capacity" when converting map

Hi,

currently I am getting a ton of crashes like this:

Any idea what might be wrong?

It happened in 3706 to 3730
Sometimes the exact same conversion process (splitting+mkgmap) on the 
exact same OSM file works, but that is rarely the case
If you need any more information, or an upload of the style and split 
tiles that cause the crash, let me know.

Hope you can help
